If the switch/hub does not have an agent and a network address their is no way you can monitor or discover it. You could use nmap for discovery of ip nodes, ethereal can also help if you can track down bpdu(Bridge Protocol Data Units) but that would be painful. If their are snmp agents and they all have IP addresses, you can map things out by their bridge tables. To be able to autmate viewing the switch/hubs interconnections, you would need an additional LLC layer protocol such as Extreme's EDP, Foundries FDP or Cisco CDP (HP also uses CDP). And then a piece of software that can read that data and map it, such as Foundry's Iron View, Extreme's Extremeware or Cisco's package. I also recall HP rolled this in to NNM version 6.X as well. Dam, I am glad I don't need no stinking maps anymore :-) Ted On Wed, 2003-11-19 at 09:50, Chiu, PCM (Peter) wrote: > Maybe I start a new query.
